Y By the provision of the extensions, of thetrougli or receiverelements, V.14, 15, 15 and press elements 30, 36. and 36, beyond thetable top and operating means a cushion easing, or cover, 39', V(seeFigure 4) may be readily placed over tieV sizing and press elementssurrounding a built up lilleiiv 'ina positionfand condition to receivethe illerf7V or moving the iiller'into the casing; l

provide a ram .comprising block 4Q, a cylinder 41 and apiston, havingarod 42, con- Vtrolled by a valve 43 tromthe source 19.-

To adapt the machine to size fillers voft different lengths the pistonrod 42 is made ot `atube and anciitension rod 44' isteles-copicallyi'itted therein and made adjustableby Y means such as the spring-dogs 45(sce Figure 9) and the relatively spaced slots, or

openings 46, located respectively in the extension rod 44 and tubularpiston rod 42.

Bv this means obviously the block may be set in different positionstorsizing cushion fillers of diil'erentlengths.

For convenience in releasingzthe doos o o a 1 provide slip collars 4a,carryingt lugsp43 arranged to move and hold the dogs in' `planes beyondthe openings 46@ For structural economy, l prefer to equip mymachine'witli a cylinder of less' length than the Vmaximumcushion lengthand forl this reason there is required means for Vreadily changingtliepiston rod length. As

By the expedient oic the 1neans`,`j`ust're cited, for operating thegreater than v the cylinder length, l am enabled tof setup my machine ina relatively limited space and provide yin the one ma chi-ne rammovements greater than the cylin-I der length. Ubviously the movement ofthe rama distance greater than the cylinder or less than the selectedsize.

ram, a distance length requires morethan one cylinder action or push anda resetting of the piston and its extension subsequent to each push orram movement.

11i-the practical operation of the machiney l after the desired cushiondimensions are determined Vthe filler sizing elements 13 are set Yforlateralsizing byinovingrthern relatively to Ya spacing equalling thelat-eral or width dimension of the selected cushion dimension, thensetting the collars 38 so that a subsequent movement of' theelenientsf13,

lLi

by means ot the cylinder 16 and associated gear, comprising thelevers20, shaft 21,`

levers 22 and links 23 will not be beyond rlthis settingbv reasonoft-herhooks 37, obviously setslthe press, or vertical sizing elements,namely the elements 36,- 35 to correspond with Jthe elements 13, 13. Irlhe machine is then setor klongitudinal sizing byy positioning theblock 40 spaced from the extremityV or" the trough, or receiver,comprising the element 15, a distance correspendingl with Vthe-:selectedlengthv rot,

cushion liller and setting the piston VVrod 42 .and extension rod 44by-,means of the springvdogs 45 and slots 46. Y n y Y -Vlith the lsizingelements so set, the operator manipulates the valve 35 and through thecylinders 33, piston rods 32 and crossshaft 31; the press, as a whole,.including the beam 29, body 30 and radjustable sizing, elements 36are-elevated, as shown by dottedv lines in Figure 1, leaving the trough,or receiver, comprising the relements 13 openf With Vthe pressthuselevated and the receiver open the elements 13 of the receiver are.moved, by a simplemanipulatioii of the 'valve 1 8, to reside inpositions relatively separated a distance greaterth'an the lateraldimensions of the cushion filler tobe made,

or built up therebetween, -so that 'ample space is allowed for suchbuilding up.

The operator then builds up a filler', betweenthe two sizing-elements 13and between the block 40 and tlie'extremity of the ltrough. After thefiller has been built up, the valve 35 is againmanipulated and the pressbrought to parallel the table thereby vertically sizing'the iiller,After thus verticallysizing the filler vthe operator manipulates thevalve 18 and through the cylinder A 16 and the recited gear associatedtherewith r:

moves the lateral sizing elements including the elements 13, 13, 15, 15,36 and 36 to their limit as determined by the set collars 33.71Atthistime the cushion casing 39 Yis pulled or telescopically litted over thepro- `iecting ends of the ti"ough',andV press elements as shown inFigure 4 in a ,position to receive the filler.

`With the cushion filler Vthus siz'edboth laterally and vertically thesizing elements are locked against relativev movements by iso plished bya simple manipulation of the valve Y 43 whereupon the block 40 or rampushes the built up and properly sized iiller into theA casing 39.

y The iinishin T of the cushion then amountsV to a mere closing of itsone open end about the end of the filler. Y

It is my preference to employ compressed air as the operating medium ofmy machine and in my drawings I have illustrated motors utilizing suchmotive fluid, but I in no sense wish to be understood aslimiting myselfto such operating means as is evidenced by the scope of my claims.

What I claim as new is l. In an upholstering machine, a table, avertical cushion sizing element, means for pivotally mounting one end ofsaid element above the table,`a valve controlled fluid actuated motorfor raising and lowering the other end of the vertical sizing element, a

pair of lateral cushionsizing elements, a valvev controlled fluidactuated motor and4 means for causing the motor to synchronously movethe lateral sizing elements, adjustable means for limiting the movementsof the lateral sizing elements in sizing directions,4 a ram, a valvecontrolled iiuid actuated motor for the ram, means for locking* certainof the sizing elements during the ac.-

tion of the ram and extensions for said lateral and vertical sizingelements over which a cushion casing may be telescopically fitted andVthrough which the built up and vsized cushion iiller is'forced to bereceived by the casing.

2. In an upholstering machine .for forming cushions of different'dimensions, comprising a table, width sizing elements associatedtherewith, means for moving said width sizing elements to predeterminedpositions on said table, a press for sizing the thicknessl of thecushions, means for moving said press relative to the table, and a ramfor sizing the lengths of the cushions comprising two relatively movablemembers and means for varying the relative position of saidmovable-members, Y

3. In an upholstering machine for forming cushions of differentdimensions, a ta-VY ble, width sizing elementsassociated therewith,means for moving said elements to predetermined positions on said table,a press.

for sizing the thickness of the cushions, means for movingsaidpresslrelative to the table, and a reciprocating Vplunger for sizingthe length of the cushions having means associated therewithrfor varyingits length.

4. In an upholstering machine for forming cushions of differentdimensions, means for. sizing the width and thickness ofl the cushionsto predetermined dimensions, and

means for sizingthe length of thecushions comprisinga plunger and afluid motor for Voperating the plunger,the cylinder of the motor being 4shorter Ythan the maximum lcushion length, said plunger having meansassociated therewith whereby it may be lengthened `to form cushions ofmaximum length.

5. In an upholstering machine for form-1J ing cushions of differentdimensions, a tav ble, means ,associated therewith for sizing the Widthand thickness of the cushions, and

means for sizing the length of Vthe cushionsv comprising a plunger and afluid, operated motor therefor, the cylinder of said motor having alength less than the `maximum .cushion length, said'plung'erliavingpmeans for varying its length, and stop means associated withsaid table fory y.preventing the 'l full return-strokel of the plungerwhereby one or more subsequent strokes of the plunger'mayY size thecushion to the desiredlength.

6. In an upholstering machine, a table, a

vertical sizing element, means for pivotallyl mounting one en d of saidelement above the table, a valve controlled fluid actuated means forraising and lowering the Vother end of said vertical sizing element, apair of lateral sizing elements, a valve controlled iiuid actuated motor.andmeans to cause the motor to synchronously move ythe lateral sizingelements, "a ram, and a valve controlled iiuid actuated motor foroperating the ram.

7. In an upholstering machine, a table, a vertical sizing element,vmeans for' pivotally mounting one end of said element above the table, avalve controlled-fluid actuated means for raising andlowering the otherend of said vertical sizing element, a pair of lateral sizing elements,aY lvalve controlled fluid actuated -motor and means for causing themotor to synchronously move the lateral sizingelements, a ram, a valvecontrolled liuid actuated motor for operating the ram, and

means for locking certainof said sizing elementsduring the operation ofthe ram.
